Best artery to palpate for pulse in infants is –
**Core Concept**
In infants, palpating a pulse is crucial for assessing cardiovascular stability. The best artery to palpate in infants is one that is easily accessible and has a relatively superficial location, allowing for accurate and reliable pulse measurement.
**Why the Correct Answer is Right**
The brachial artery is the best artery to palpate for pulse in infants due to its superficial location in the upper arm. This artery is easily accessible and provides a clear, palpable pulse. The brachial artery is a continuation of the axillary artery and is located in the cubital fossa, making it an ideal site for pulse palpation in infants. The brachial pulse can be palpated in the medial aspect of the upper arm, about 1-2 cm proximal to the antecubital fossa.
**Why Each Wrong Option is Incorrect**
* **Option A:** The radial artery is another commonly used site for pulse palpation, but it is not the best choice in infants due to its smaller size and more difficult accessibility.
* **Option B:** The femoral artery is located in the groin area and is not easily accessible in infants, making it a less desirable site for pulse palpation.
* **Option D:** The carotid artery is located in the neck and is not typically used for pulse palpation in infants due to its deeper location and potential for complications.
**Clinical Pearl / High-Yield Fact**
In infants, the brachial pulse is a reliable indicator of cardiac output and should be checked in conjunction with other vital signs to assess overall cardiovascular stability.
**Correct Answer: C. Brachial artery.**
